Tatsurion the Unchained/Rulings

Q: Say Tatsurion the Unchained attacks, wins a battle, and untaps. Can I attack with it again that turn?

A: Yes. You can attack with a creature multiple times in a turn if you find a way to untap that creature between attacks.

Q: Tatsurion the Unchained has 6000 power. Say it attacks a creature that has 3000 power. It wins that battle and untaps. Then it attacks another creature that has 3000 power. Will Tatsurion the Unchained be banished in the second battle?

A: No. A creature is banished in a battle only if it has the same power or less power than the other creature. What happens in one battle doesn’t carry over to other battles that turn.
